If you go out in the morning, you can buy few simple food in the street. And also always bike is ready so it will take you to the place you want.
There is 24hrs fruit store nearby but not recommended. Watermelon that I bought was not tasty and more expensive than the one from mart.
There is washing machine and detergent but no place to dry so you should go facility floor and dry them with 100. ( you have to change with coins first. You can change it from office in the 1st floor )
There is a good restaurant nearby, lemongrass. Cheap and clean.
